Neighbourhood Security Residential Street Patrols. Crown Protection Services (CPS) pioneered the Neighbourhood Street Patrol and for over a decade has maintained itís position of one of the leading security providers in the UK. Although there have been many copycats. We provide a fully trained SIA Licensed and uniformed security officer with a patrol dog and a marked security vehicle. Our officers have mobile handsets to enable residents to communicate directly with the officer and our Control Centre, which allows participating residents a further point of contact 24 hours a day, 365 days a year.
